COMMENTS

This product is a classic oral paste dewormer for horses from ELANCO with pyrantel.

Pyrantel is a veteran tetrahydropyrimidine introduced in the 1960s (by PFIZER → ZOETIS) that is moderately used in horses, abundantly in pets, but rather scarcely in ruminants. It is a narrow-spectrum anthelmintic effective against roundworms and a few tapeworms in the gut, but not against those in other organs (e.g. the lungs, the skin, etc). It is also ineffective against gastric bots (Gasterophilus spp) or whatever external parasites. 

Pyrantel has no residual effect, i.e. it kills the parasites after administration but does not protect against reinfestations. In year-round control programs the recommended treatment interval is usually 4 to 6 weeks.
